HubSpot's COS landing pages require a value in the name, page title, and page url boxes before the Publish option will appear in the editing interface.
If your landing page is not published, or if the publishing option is not present:
- In your HubSpot Marketing account, navigate to Content > Landing Pages.
- Locate and hover over your desired page in the landing page list > select Edit.
- Click Settings at the top of the page to view the current values for those sections.
- Once the page has the required elements, you will be able to select Publish at the upper-right hand corner to publish immediately or select Publish or Schedule to schedule the page for publishing.
Please note: any page you publish must have a unique URL. If the URL you give to your landing page is already in use by another one of your live or draft pages, you won't be able to publish your page. See this article for more information.
